Abstract

The invention discloses a Bacillus subtilis strain and application thereof. The strain is named as Bacillus subtilis ZJU007 and preserved in the China general microbiological culture collection center (CGMCC) of Chinese Academy of Sciences on yard No.1 on Beichen West Road, in Chaoyang district in Beijing on September 3rd, 2010, and has the preservation number of CGMCC No.4140. A bactericidal substance generated by the strain of the invention has very strong inhibition effect on Candida albicans and has better bacteriostasis effect compared with common fungicidin. The bactericidal substance not only has very strong bacteriostasis effect on the Candida albicans and other yeast like fungi, and the like, but also has excellent effect on Aspergillus niger and other filamentous fungi, and meanwhile, has better bacteriostasis effect on escherichia coli and other bacteria.

Description

technical field

[0001] The invention relates to the technical field of bioengineering, in particular to a bacillus subtilis strain and an application thereof. Background technique

[0002] In recent years, with the improvement of modern medical treatment, the survival rate of patients with cancer, AIDS, organ and bone marrow transplantation has increased greatly. Chemotherapy, venous catheterization, hemodialysis and other interventional treatments lead to decreased immunity, and are easily invaded by conditionally pathogenic fungi that are not originally pathogenic, causing deep mycoses (Systemic fungal infection). In recent years, this serious life-threatening fungal infection has shown a rapid growth trend, and the number of patients has continued to increase.

[0003] Clinically, with the increase of fungal infection rate, the utilization rate of antifungal drugs has increased, and the drug-resistant strains have also increased, which brings certain difficulties to clin...
